According to law of conservation of mass, mass can neither be created nor destroyed in a chemical reaction.
Sodium hydrogen carbonate + Ethanoic acid → Sodium ethanoate + Water + Carbon dioxide gas
NaHCO3 + CH3COOH → CH3COONa + H2O + CO2
(4.2 g) (3.0 g) (4.1 g) (0.9 g) (2.2 g)
i.e. 4.2 g + 3.0 g → 4.1 g + 0.9 g + 2.2 g
LHS: 7.2 g = RHS: 7.2 g
These observations are in agreement with the law of conservation of mass because in this chemical reaction, total mass of reactants is equal to total mass of the products.
